SILO.

Speccation of Letters Patent.

Application filed March 7, 1912. Serial No. 682,187.

To all whom t may concern.:

Be it known that I, PERCY J. HINDMARSH, of the city of Lincoln, county of Lancaster', andState of Nebraska, have invented certain new and useful Improvements in Silos, andehave described the same in the following speciication, illustrated by the accompanying drawings.

My improvements relate to that class of silos in which the discharge of ensilage is ettected by the instrumentality ot' an internal vertical chute. To thesame class belongs the silo shown in my copending patent application No. (H5358 filed. August El, 1911.

It is the object of the invention to render a silo otl this class cheap and inexpensive to manufacture; to use the space within the silo economically; to facilitate supplying` the chute with ensilage from dilierent levels in the silo; and in general to produce a superior silo of the specified class. To this end I incorporate in my improved silo a tubular chute of adjustable length and a vertically suspended ladder dependent within the chute and detachably engaging the same for4 its support.

The best manner in which have contemplated applying the lprinciples of the invention is shown 1n thedrawingsnyet the invention itself is not restricted to any spe# cie arrangement or construction of parts, excepting in so far as limitations of that kind are eitherl expressed or necessarily implied in the subjoined claims.

Figure 1 of the drawings is a side elevation of a typical silo of the specified class, embodying these principlesparts of the structure being removed to show the-inn ternal arrangements. The remaining tigures are enlarged details. Fig. 2 is a perspective view of one of the several cylinders or sections composing the chute. Fig. 3 is an axialllsection of several of those cylinders attached in operative positions tothe supporting ladder vshown i'nfront elevation therein'. Fig. 4 is aside elevation of the ladder. Fig. 5 is a horizontal section on the section line a-o of Fig. 3. Fig. 6 is a side elevation of the delivery chamber at the base of the chute. Fig. 7 is a front elevation of the same.

The illustrative silo of these figures co1nprises the ordinary cylindrical shell 1, roof 2. roof entrance 3 and outside ladder 4. The inside adder 5 having top hooks' 6,

depends thereby from the supporting framework 7 near the roof. It consists otl the detachable sections 8 bolted together in assembling, and has the hooks 9 pivoted on its alternate rungs 10. The chute 1Q comprises the telescoping metalliccylinders 11 having the engagement holes 13 for the accommodation of these hooks. By these the cylinders are hung on the ladder and unhung by hand as occasion requires.

To keep the top ofthe chute continually in the silo, andtherebyto facilitate supplying ensllage to the chute from successive above the lowest are by hand unhooked from the ladder one at atime in succession, beginning at the top, and are dropped or pushed telescopingly each into the next below, as required by reason ot the falling level of the ensilagc .in the silo, and are stopped one within another by the mutual contact of the terminal liangcs 13 of the concentric cylinders. T e chute opens downward into the delivery chamber 14, and encircles the upstanding flange 17 on the top of that chamber. rlhe latter,` being through which the fodder may be thrown by hand when the supply in the silo is low, and an outside door 16 through the shell l, through which the fodder may be removed for consumption. Economy of space within the silo is effected by the eccentric location of this chamber and by using the chamber and the extended chute as a continuous receptacle for the storage of the ensilage when the silo is full. Economy and strength of construction are effected by dispensing with the usual outside chute and the usual series of outside doors, one above another, through the .side of the silo.

. I claim as my invention- 1. A'. silo comprising a vertically supscoping sections encircling'the ladder, and means for supporting the sections individu-- ally from the ladder.

2l A silo comprising a ladder support, a ladder dependent therefrom, a chute having telescoping sections surrounding the ladder, and means for att-aching the sections individually to the ladder.

3` A. silo, comprising a lixed ladder support in the top of the silo, a ladder dependlent from the fixed support, and a chute within reach frotn the top of the e'nsilage ported ladder, a tubular chute having telechanging levels, all the chute cylinders within the silo, has an inside door 15 having a plurality of telescoping sections encircling the dependent ladder, in eoinbination With means for supporting the telescoping sections severally from the encireled dependent ladder.

4: A silo, comprising a fixed ladder support in the top of the silo, a ladder dependent from the fixed support, a chute of adjustable length formed of telescoping sections encircling the vdependent ladder and detachahly suspended thereon, and a. delivery chamber fitted to the bottom of the chute and opening through the external shell of 'the silo.

In testimony whereof I hereto subscribe 15 my name in the presence of two Witnesses. PERCY J. HNDMARSH. Witnesses:
